Application filed April. 14,

To all whom it mag concern. 7 Be it known that l, J OHN OLson, a citizenof the United States of America, residing at Detroit, in the county ofWayne and State 5 of ivlichigan, have invented certain new and usefulImprovements in Float-Controlled Valves, of which the following is aspecifi cation, reference beingha d therein to the accompanyingdrawings.

This invention relates to a valve particularly adapted for use in thewatercontainer used in hot air furnaces for humidifying the air. p i

It has for its object to simplify the con- 15 struction of such valves,to provide convenient means by which the valve passages may b cleaned ifobstructed in any manner'and otherwise to improve valves ofjthis classas will appear hereinafter in the description.

l'n the drawing,

Figure 1 represents a central longitudinal section of my improved valveapplied to a tank or receptacle; v K

Fig. 2 is a perspective viewof the hinge member for supporting the floatarm; and

Fig. 3 is a fragmentary perspective View of the end portion of the floatarm.

The valve consists of a body member 1 preferably consisting of a solidpiece of metal not affected by rust or heat, one end of the body beingscrew threaded as at 2, to receive a nut 3 and a connection 4, waterentering through said connection from any suitable source of supply. Thebody 1 is provided with a longitudinal bore 5, the inner end of which isenlarged and internally threaded to receive a plug 6. A transverse boreis formed with a small inner portion 7 communicating with the bore 5 anda larger outer portion 8 within which is mounted a metal valve plunger 9preferably formed as a square rod having a conical inner end 10 adaptedto close the passage 7.

A hinge member or plate 11 consisting of a flat piece of metal has aperforation 12 to receive the body-1 of the valve. The hinge member 11is seated against a shoulder 18 on the body 1 and a washer 14 is placedon the body against the hinge member 11. When the nut 3 is made tight,the washer 14 is compressed between the plate 11 and the end wall 15 ofthe tank, the valve thus being held firmly in place and the joint beingmade water tight.

The lower end of the member 11 has a flange ofi'set inwardly from thewall 15 and 1921. Serial No. 461,301.

' downwardly from the'body 1, a slot 16 being formed in the dependingflange to receive th bent end 17 of the float arm 18. As shown in Fig.l, the bent end 17 is'of such come accidentally detached. The end 17must b placed through the slot 16before the plate 11 is set in positionon the valve body 1. A recess 19 is formed in the upper 1 ed a surfaceof the arm 18 to receive the roun lower end ofthe valve plunger 9.'VVhen water enters through the port 7 it flows out through the bore 8,the flat sides of the plunger 9 providing passages on all sides of theplunger.

When the float 20has been pushed up:

'60 a length as to engage the wall 15 before the ward by the waterflowing into the tanki the arm 18 presses the plunger 9 upward, forcingthe'conical end 10into the passage 7to forma tight closure and preventthe entry of water until some of the water in the tank has evaporatedfrom the surface.

From the above description it will be apparent that there is thusprovided a device of the character described, possessing the particularfeatures of advantage before enumerated as desirable, but whichobviously is susceptible of modification in its form, proportion,details of construction and arrangement of parts without departure fromthe principle involved or sacrificing any of its advantages. I

While in order to comply with the statute the invention has beendescribed in a language more or less specific as to structural features.it is to be understood that the invention is not limited to the specificdetails shown, but that the means and construction herein disclosedcomprise but one of several modes of putting the invention into effect,and the invention is therefore claimed in legitimate and valid scope ofthe appended claims.

I claim 2- 1. A float valve comprising a body having alongitudinalperforation throughout its length. a removable means forclosing the inner end of the perforation, a transverse bore through theside of the body communicating with the longitudinal bore, the innerportion of the transverse bore being smaller 7 any of its forms ormodifications within the g than the outer portion, a valve plunger longitudinally slidable within the outer portion of the transverse bore andhaving its inner end of a configuration to close the smaller portion ofthe b0re,'a float arm having a bent end, a hinge member comprising aplate having an opening therethrough, adapted to receive the body of thevalve and having a second opening spaced from the firstopening andadapted to receive the bent end of the float arm, the said float armhaving a recess adapted to engage the outer end of the valve plunger anda float secured to the outer end of the float arm.

2. A combination with a tank having an opening in one wall thereof, of avalve having a body externally screw threaded from oneend, a float armhaving a bent end, a

hinge member havlng a lower depending por- I tion perforated to receivethe bent end of the float arm, and positioned adjacent to the inner faceof the tank wall, a nut engaging the screw threaded portion of the valvebody and bearing against the outer face of the tank wall, the bent endof the float arm lying substantially parallel with the wall of the tankand being of a length greater than the distance from the wall of thetank-to the depending perforated'portion of the hinge member whereby toprevent removal of the float arm from the hinge member when the valvebody is attached to the tank.

. 3.- The combination with a tank having an opening in one wall thereof,of a valve, the body of which is reduced for a portion of its length toform a shoulder, a hinge member surrounding the body of the valve andengaging the shoulder, the outer end of the reduced portion being screwthreaded to receive a nut and a pipe connection, the nut acting to clampthe hinge member between the wall of the tank and the shoulder, the bodyof the valve having a longitudinal perforation adapted to communicatewith the pipe connection and closed at the end within thetank by aremovable closure, a transverse bore in the lower side of the valve bodyhaving a reduced inner end, communicating with the longitudinalperforation, a valve plunger of non-circular cross section mounted toslide in the transverse bore and having its upper end adapted to closethe reduced inner portion of the bore and a float arm engaging the hingemember at one end and having a float at the end remote from the hingemember, the float arm having a seat formed to engage the outer end ofthe valve plunger to hold it in operative position.

In testimony whereof I afiix my signature in presence of two witnesses.
